Chemical Structure
Description
As a certified reference material (CRM), 1-(4-(1-(2,4-Difluorophenyl)-1H-pyrazol-5-yl)phenyl)-3,3-dimethylazetidin-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1-(4-(1-(2,4-Difluorophenyl)-1H-pyrazol-5-yl)phenyl)-3,3-dimethylazetidin-2-one (CAS 320422-75-1) is a high-purity analytical reference standard with the molecular formula C20H17F2N3O and a molecular weight of 353.37 g/mol.
1-(4-(1-(2,4-Difluorophenyl)-1H-pyrazol-5-yl)phenyl)-3,3-dimethylazetidin-2-one (C20H17F2N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
